When sysrq is triggered from console, serial driver for SUN hypervisor console receives a console break and enables the sysrq. It expects a valid sysrq char following with break. Meanwhile if driver receives 'NULL' ASCII char then it disables sysrq and sysrq handler will never be invoked. This fix skips calling uart sysrq handler when 'NULL' is received while sysrq is enabled. Signed-off-by:
